a w/wrn it may concern Be it known thatI, MARVIN A. NEELAND, ofYoungstown, Mahonin r county, Ohio, have invented a new and usefu Valvefor Blowing- Engines, &c.', of which the following is a fit l, clear,and exact description, reference being had to the accompanying drawings,forming part of this specification, in which Figure 1 is atop plan viewshowing one form of my improved valve. Fig. 2 is a crosssectional viewon the line II II of Fig. 1, showing thevalve in closed position. F 3 isa view similar to Fig' 2, showing the valve in open position. Fig. 4 isa to plan view showing another form of the va ve. Fig. 5 is alongitudinal section or" the form of Fig. 4. Fi 6 is a view similar toFig. 5, showing the va ve in open position; and Figs. 7 and 8 arepartial plan views of the head of a blowingen in'e, showing difierentarrangements of the va ves of Fig. 4.

My invention relates to that type of valves valves aretormcd by cuttingstrips from the valve-body. v

. The object of the invention is to give a substantially parallel liftto the valve] and uni-,

'iorrn bending of the valve-stripand to r0- vide guards for the valvewhich will a low passage of the air theretllrough, as well as around thevalve,

In the drawings,referring to the form of Figs. 1, 2, and 3, 2 Srepresentvalve-ports arranged intwo annular series. 4 is the valve, whichconsists of a thin sheet-Inetaldisk with curved spring portions 5 cuttherel'rom, these curved springs lying intermediate between the twoseries of ports. As shown in Fig. 1 the side edges of this cut strip arenot'parallel, but are tapered from both ends toward its central portion.The end portion of each strip is secured by a screw-bolt 6 or othersuitabledevice to the head of the compressor or blowingengine cylinder.In the rear of the valve is a back-stop 7, consisting of a plate ofcircular form, secured by a screw-bolt 8, extending through its centralportion and through the valve into the cylinder-head. Thisback-stop isprovided with curved ports 9', which are ar ranged in' two annularseries out of registry with the ports in the head.

In the normal position of the valve the spring-strips hold the valve in.closed position, F ig. 2, and when pressure is brought upon the lowerside or suction exerted on the of Fig. 3. In this opening movement,owing to the tapered form of the sprin the bending action of thespring-strips will be uniform and regular, thus preventing excessivestrain and injury. to the springs. When the pres sure or suction isreleased, the springs again draw the valve to itsseat.

In the form of Figs. 4, 5, and 6 the valve is in the form of arectangular strip 10, having at one end a spring-strip 11, secured at 12to the valve-seat or cylinder-head. The springstrips 13 aresubstantially the same as those of the first form, except that theextend straight instead of on a curve. T e r ends are secured to thecylinder-head, as before,

ports 14, the closed position being shown in Fig. 5 and the openposition in Fig. 6. In Fig. 7 I show one arrangement of these valves ofFig. 4 on a blowing-en ine head in which they extend parallel wit eachother. In Fig. 8 I show another form in which the ward the circumferenceof the head.

The advantages of my invention result from the tapering form of theintegral sprin also from the back stop or guard, which a lows thepassage of air past each edge of the valve from the closing of the valveby the The valve is simple an cheap and not'liable to get out of order.-l

Variations may be made in the form and arrangement of the valve, thespring-strips, &c., without departing from my invention.

1.. In a blowingen inc or compressor, a thin sheetmetal va ve having ata ered spring described. I

2. In a blowing engine or, compressor, a thin sheet-metal valve havingspring-strips out of registry with the air-ports, said strips 3. In ablowing-engine or compressor, a thin sheet-metal plate with integralsprings cut therefrom, the endof each s ring being secured to thecylinder-head, an the spring being tapered from each end toward itscentral portion; substantially as described.

' i. A blowing-engine or compressor having a valve comprising a thinsheet-metal late having strip springs out therefrom an free upper sidethe valve will lift into the position valves extend radially from thecenter to integral therewith; substantial y as being tapered;substantially as described.

at ne end, and a back-stop having ports in and they are placed betweenthe series of springs and the substantially uniform lift, due -to theshape and arran ement of the springs;

5. In a, blowing-engine 'or compressor, an. airwelve consisting ofper-ellelstrips of thin (sheet metal united at intervals, with taperedgsprings between and integral with said strips, and a back-stop arrangedto limit the lift of ithe valve and permit passage of air past each edge5 substantially as described.

6. In a blowingengine or compressor, a thin sheet-metal Valve havingintegral strips the s rings; Substantially as eut therefrem "with theirfree ends secured to the piete eenteining valveports, and ranged. tonormeaiy drew the valve to its seat substantieliy as described.

In testin'iony whereof I have hereunto set my hand.
